Question

Yii

There is a widget in the yii2-authclient extension, here it is specifically here is a widget
I need to redo the method for displaying buttons this public function clientLink
I created another widget with this method like this

<?php
/**
 * @link http://www.yiiframework.com/

 * @license http://www.yiiframework.com/license/
 */

namespace frontend\widget;

use yii\base\InvalidConfigException;
use yii\base\Widget;
use yii\helpers\Html;
use yii\authclient\ClientInterface;
use yii\authclient\widgets\AuthChoice;
use yii\authclient\widgets\AuthChoiceItem;


class MyAuthChoice extends AuthChoice
{

    /**
     * Outputs client auth link.
     * @param ClientInterface $client external auth client instance.
     * @param string $text link text, if not set - default value will be generated.
     * @param array $htmlOptions link HTML options.
     * @return string generated HTML.
     * @throws InvalidConfigException on wrong configuration.
     */
    public function clientLink($client, $text = null, array $htmlOptions = [])
    {
        $viewOptions = $client->getViewOptions();

        if (empty($viewOptions['widget'])) {
            if ($text === null) {
                $text = Html::tag('span', '', ['class' => 'blabla ' . $client->getName()]);
            }
            if (!isset($htmlOptions['class'])) {
                $htmlOptions['class'] = $client->getName();
            }
            if (!isset($htmlOptions['title'])) {
                $htmlOptions['title'] = $client->getTitle();
            }
            Html::addCssClass($htmlOptions, ['widget' => 'auth-link']);

            if ($this->popupMode) {
                if (isset($viewOptions['popupWidth'])) {
                    $htmlOptions['data-popup-width'] = $viewOptions['popupWidth'];
                }
                if (isset($viewOptions['popupHeight'])) {
                    $htmlOptions['data-popup-height'] = $viewOptions['popupHeight'];
                }
            }
            return Html::a($text, $this->createClientUrl($client), $htmlOptions);
        }

        $widgetConfig = $viewOptions['widget'];
        if (!isset($widgetConfig['class'])) {
            throw new InvalidConfigException('Widget config "class" parameter is missing');
        }
        /* @var $widgetClass Widget */
        $widgetClass = $widgetConfig['class'];
        if (!(is_subclass_of($widgetClass, AuthChoiceItem::AuthChoice))) {
            throw new InvalidConfigException('Item widget class must be subclass of "' . AuthChoiceItem::AuthChoice . '"');
        }
        unset($widgetConfig['class']);
        $widgetConfig['client'] = $client;
        $widgetConfig['authChoice'] = $this;
        return $widgetClass::widget($widgetConfig);
    }


}

Leg widget is not working now, why? although with vardump that the AuthChoice widget and MyAuthChoice show the same object
What's wrong?

Answer 1

Can you write down what you changed? Everyone has to compare your code with the original?
I don't think this part of the code is correct:

$widgetClass = $widgetConfig['class'];
        if (!(is_subclass_of($widgetClass, AuthChoiceItem::AuthChoice))) {
            throw new InvalidConfigException('Item widget class must be subclass of "' . AuthChoiceItem::AuthChoice . '"');
        }

Must be
AuthChoiceItem::class
